Water to be filtered is piped into and channeled around the periphery of the tank of the gavity strainer 4000 series. It flows upward and over a weir assembly for even distribution over a fine screen (75 to 355 micron or 40 to 200 mesh). The water is filtered leaving fibers and solids on the screen. Clean water is collected in the strainer’s bottom and flows from the unit. A continually rotating shower above the screen washes the rejects toward the center opening and the reject pipe for discharge. The strainers are especially effective separating difficult fibrous material from process water streams.
